Sure! The metaphase stage in the cel is the third step in mitosis. The chromosomes line up in the middle of the cell due to the fact that the spindle fibers pull them towards the middle (the chromosomes are in a single file line). In addition, the spindle fibers connect to the centromeres. Hope this helps :)

Answer:
The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.

The blood osmotic pressure of marine teleosts is about <u>600</u> mOsm <u>higher </u>than the environmental osmotic pressure.
Osmotic pressure is the minimal pressure required to prevent the inward flow of a solution's pure solvent across a semipermeable membrane. It is also described as the measure of a solution's capacity to take a pure solvent through osmosis.
All freshwater organisms maintain hyperosmotic blood osmotic pressures in fresh water. Blood osmotic pressure in freshwater teleosts is 300 mOsm higher than freshwater osmotic pressure.
Teleost is most hyposmotic to seawater. Because marine teleosts are hyposmotic to saltwater, they experience osmotic loss of water and NaCl diffusional gain through the gill.
